Abstract (en)

[origin: EP3315253A1] Provided is a rotary machine tool such as an end-mill, drill, tap or the like, with which it is possible to measure, in real time, the damage, breakage or extreme wear thereof, without performing a special process or the like. The rotary machine tool equipped with sensor for real-time detection of state of the present invention is connected to the tip of a rotary machining device that can rotate about a rotary axis, and rotates about the same rotary axis, the tip coming into contact with the member to be machined, thereby cutting the member to be machined. The rotary machine tool is provided with at least: a sensor installation hole which has a vertically long shape having a central axis line approximately centering on the axis of rotation, the rear end being open to the exterior at the rear end of the main body of the rotary cutting tool, and the tip being above the tip of the main body of the rotary machine tool and closed off from the exterior; a sensor that is inserted from the rear end of the sensor installation hole, is positioned at the tip of the sensor installation hole and detects the state at the positioned position; and a sensor insertion hole that is connected to one end of the sensor and is coupled with the rear end of the rotary cutting tool.
